Cheap liquid cooling

Okay, so I am building a little box that my computer will sit on in my trunk ( about an inch high) to put some radial fans, blowing cool air from the sides of the box to the underside of the computer.

But I am wondering is there a cheap liquid cooling solution, that is also rather small, to just help out with cooling. I am not worried about the physical aspects (size and such) but just what it can do.

Also, do you have something to cover it up so that stuff can be piled on top, or is that space lost for cargo use?

As for doing water cooling in a small case- tricky, but possible.

There ARE some very small systems around, but I'm not sure that even THEY would fit in a case intended for carpc use. And the performance is less than stellar (without modifications!) But if you have room to mount a pump and rad outside the case all you really need is a compact water block or two, and a bit of creativity.

Thanks...
The fans on the rad blow in...the other fans are for the parking lot
There is a speaker cloth covered piece that covers the PC, yes...but not the amps.

The radiator and such would be outside the pc. Just a tube going into it. Which I would make sure has an exelent seal.

First of all, there will be at least one water block mounted to the CPU. Depending on the setup, you may have additional waterblocks on the motherboard chipset and/or GPU as well.

There is a reason quality liquid cooling components are pricey. They are well engineered and manufactured with precision.
In order to make them less expensive, corners are cut somewhere, possibly with quality.

I'm not you, I know.
But if it were me, I wouldn't want to go with budget water cooling for any PC, let alone one in the car. If that cheap component winds up being defective out of the box, you are risking destroying that hardware.
If that hardware is in your car, you're risking an electrical hazard and a hire hazard.

WuNgUn- well done indeed. I have seen (and done myself) some water cooled desktops that weren't as well done based on appearances.
My only other comment is to ask if you ever tried the fans the other way: pulling into the computer/mobo airspace will get you the best H2O block temps, but will increase mobo temps a bit too. The other way will reverse that. I have used both in different systems, depending on temps and how the systems ran.

DarquePervert makes good points, no doubt: a cheaply made part IS far more likely to fail, and I have seen some cheap crap over the years.

But there used to be inexpensive yet good parts around too; performance was not as good as a rule, but except for heavily overclocked and/or modded machines some of those parts can do pretty well.

For a cheap system, you may do well looking at the "Clearance" sections of the water cooling vendor sites, and perhaps some of the better modding/hardware sites.

You would need a well-made block and decent pump, and something sufficient for a radiator.
